Samsung bootloader unlock warning screenWhen you unlock the bootloader on a Samsung smartphone, you always get a warning screen each time the smartphone is turned on letting you—and everyone else who sees your screen—know that the bootloader has been unlocked. I remember the first time I unlocked the bootloader on my Samsung smartphone, and I must admit, it was a turn-off to know I had done something that created that warning message. It made the smartphone feel less premium, and I regretted it as soon as I knew I had unlocked it for no reason because the rooting method never worked for me anyway.

Thankfully there is actually a way to remove the bootloader unlock warning on Samsung with the use of a Up_Param.tar file. This method was first found by Sayyed Raza of RazsOriginals. Here are the steps:

How to Remove Bootloader Unlocked Warning Samsung

You can remove Samsung’s unlocked bootloader warning that you get after unlocking the smartphone’s bootloader with a modified Param file. Here is how to do that:

1. Download a terminal for your Samsung smartphone. Termus is recommended but not necessarily the only one that works.

2. Download the Param file and transfer to the Download folder of the Samsung smartphone.

3. Open terminal and gain root access using su.

4. Type the following command into the command line and execute it:

dd if=/storage/emulated/0/Download/up_param.tar of=/dev/block/platform/bootdevice/by-name/up_param

5. Reboot the Samsung smartphone to Recovery Mode.

6. Reboot out of Recovery Mode and back into the standard operating system where you would use Android.

In conclusion, that is how to remove the bootloader unlock warning on Samsung smartphones. We don’t link to apps anymore in general because the links become broken over time. But you can open Google Play and type “Termus” to download that terminal app if you need it. Let us know in the comments how you went or if you have any extra tips.
